Every campaign,in perfect alignment.

Meton Labs builds SignalFlow, a review-first workspace for marketing agencies. Plan posts for each client brand, draft them with the AI model you choose, approve every word, and publish on schedule through official platform APIs.

How it works

One cycle, four phases

Every post in SignalFlow moves through the same four phases. AI does the drafting. A person makes every decision that reaches the public.

New moon

Plan

Set up each brand once: its voice, its channels and its media. The Automation Planner then sets how many posts go out per day on each platform, the image and video mix, and the exact time of every post.

First quarter

Draft

When a post is due, SignalFlow drafts one version per channel in the brand's voice. You choose the model: Gemini, ChatGPT, the OpenAI or Gemini API, or write it yourself.

Waxing gibbous

Review and approve

Every draft lands in a review inbox as "Needs review". Before anything can be scheduled, a preflight check confirms the channel is connected, the media is reachable and the post type is supported.

Full moon

Publish and track

Approved posts publish through the official Meta Graph API. Each job carries an idempotency key, so a retry can never post the same thing twice, and every result is recorded against the brand.

Product

The review inbox is the heart of SignalFlow

Agencies run many brands at once. SignalFlow keeps each brand's queue, voice and approvals apart, and shows exactly why a post is or is not ready to go.

Illustration with sample data. The brand and post shown are examples, not a customer.

Client and brand workspaces

Organise work as client, brand and channel. Each brand has its own voice, media library, schedule and approval history.

Automation Planner

Posts per day, image and video mix, and a time for every post, set per platform. Due posts become drafts for review, never automatic posts.

Your choice of AI model

Draft with Gemini or ChatGPT subscriptions, the official OpenAI and Gemini APIs, or by hand. Every draft records which model wrote it.

Approval gate and preflight

Nothing is published without a human approval. Preflight blocks posts with missing media, a disconnected channel or an unsupported format.

Official publishing, safe retries

Facebook Pages publish through the official Meta Graph API. Idempotency keys and retry states stop duplicate posts when a network call fails.

Credentials stay on your Mac

Platform tokens are stored in a user-only file on your computer. The app interface never reads them, and SignalFlow never copies browser cookies or passwords.

Our name

Named after an astronomer from 432 BC

Meton of Athens noticed that 19 years on the sun's calendar almost exactly match 235 cycles of the moon. After that span, the sun and the moon meet again on the same date. We build for that kind of alignment: the right message reaching the right audience at the right moment.

Our mark follows the same idea. Every circle in it is sized by a power of the golden ratio, and the sun sits exactly on the horizon line where the arches begin.
